The headlights still worked and the dealership service center couldn't find anything so they reset the warning and said to come back if it comes back on.

It's been a couple weeks and the warning is back. I just don't want to pay for another diagnostic and not find anything. Or pay a ton to fix something that isn't causing an actual, noticeable problem.

The warning is annoying because it keeps popping up and blocking the screen on the dashboard.

What would you do?
